(Figure 91)

Material: 5 specimens in total. Roxas (3) RGM 962301, RGM 962302 , RGM 962303 ; Tiep2 (2) RGM 962304 .

Rectangular otoliths (OL:OH=1.26–1.30) with a slightly outward bent dorsal ventral and anterior rim and a concavely bent posterior rim, which is separated by a pronounced postdorsal angle. The medial sulcus is beanshaped and depressed and is covered by a colliculum. The crista inferior is visible in one of the specimens and displays a thin regular thickening except for the posterior 20%. In this well-preserved specimen, the crista inferior connects to a small ostial fold that does not reach the anterior rim. The inner surface around the sulcus is convexly elevated, demarcated by an indistinct ventral furrow and an obliquely linear boundary halfway the dorsal field. The outer surface is smooth and strongly convex in dorso-ventral direction.

The otoliths resemble the Pliocene otoliths of ‘ Gobiidarum’ weileri Bauza Rullan, 1955 in general outline, sulcus, and the shape of the elevated area around the sulcus, but differ by a smoother inner surface. They probably represent a new unknown species.
